Earth is about 93 million miles from the Sun but only 239,000 miles from the Moon. Likewise, the Sun has a mass that is over 20

million times that of the Moon. Earth experiences a strong gravitational attraction to both of these bodies, but for two different reasons. Using what you know about the factors that influence gravity, what specific characteristic or characteristics contribute to the attraction between Earth and the Moon? What specific characteristic or characteristics contribute to the attraction between Earth and the Sun?

Answer:

Gravity is dependent on the mass of two bodies and the distance between them. There is a strong gravitational attraction between Earth and the Moon because they’re relatively close to one another. There is a strong gravitational attraction between Earth and the Sun because the Sun is so massive

Use conservation of momentum ;

m1u1 + m2u2 = m1v1 + m2v2

1200×15.6 + 0 = 2700v

v = 18720/2700

v = 6.933 or ~ 7 m/s

Naya [18.7K]

Answer:

The center of the Milky Way most likely contains a supermassive black hole.

Explanation:

Because it is  an eleptical galaxy, it has a little rotation to it but not enough to flatten out so the center will contain a supermassive black hole.

Light of wavelength 530.00 nm is incident normally on a diffraction grating, and the first‑order maximum is observed to be 33.0∘
GarryVolchara [31]

Answer:

1028 slits/mm

Explanation:

We are given that

Wavelength of light, \lambda=530nm=530\times 10^{-9} m

1nm=10^{-9} m

\theta=33^{\circ}

n=1

We have to find the number of slits per mm are marked on the grating.

We know that

dsin\theta=n\lambda

Using the formula

dsin33^{\circ}=1\times 530\times 10^{-9}

d=\frac{530\times 10^{-9}}{sin33^{\circ}}

d=9.731\times 10^{-7} m

1m=10^{3}mm

d=9.731\times 10^{-7}\times 10^3mm

d=0.0009731mm

Number of slits=\frac{1}{d}

Number of slits=\frac{1}{0.0009731}/mm

Number of slits=1028/mm

Hence, 1028 slits/mm are marked on the grating.

A pair of slits, separated by 0.150 mm, is illuminated by light having a wavelength of λ = 643 nm. An interference pattern is ob
kumpel [21]

Answer:

0.006 m

Explanation:

d = separation between the slits = 0.150 mm = 0.150 x 10⁻³ m

λ = wavelength of the light = 643 nm = 643 x 10⁻⁹ m

D = distance of the screen where interference pattern is observed = 140 cm = 1.40 m

δ = Path difference

Path difference is given as

δ = Dλ/d

δ = (1.40) (643 x 10⁻⁹)/(0.150 x 10⁻³)

δ = 0.006 m
